Downloading and activating microcode involves the following steps:
1) Download: The application client transfers microcode to the device server in one or more WRITE BUFFER commands;
2) Save: After receiving the complete microcode, if defined by the download microcode mode, the device server saves the microcode to nonvolatile storage; and
3) Activate: After receiving the complete microcode and after saving it to nonvolatile storage if defined by the download microcode mode, the SCSI target device begins using the new microcode for the first time after an event defined by the download microcode mode.

Said very arid, my ‰ЏЋ procedure, everybody analyzes, possibly the ratio listens to me to say also can have the harvest.
This is the SEAGATE one section of promotion procedure (partial), now should also be allowed to use. The resources document does not know which table of contents put to in, later will find comes up again.
From this section of procedure s.scsi_command [ 0 ] = 0x3b... 0x05... 0x07 may see, the promotion process actually is one transmission process, first delivers the code in BUFFER carries out, the behind
instruction is the condition surveillance.
To the hard disk said is needs the special way carries on the transmission promotion code, otherwise, your code could regard as by the hard disk DATA writes on the plate piece.
The translation is uses BC 3.1, states: Same year very are many with SEAGATE hard disk correlation software mostly uses or profits from this section of procedure, therefore the movement flow has the similarity
in the certain degree and other software, even the window position all same. Promotes the FIRMWARE process is specially simple, really has no new pattern to be allowed to advance in the procedure, the
WINDOWS version also may do the window flowered smart somewhat. But, this procedure has the copyright, please everybody do not have to be left intact copy, understands after was allowed the transformation,
only if were under the authorization only then can copy verbatim issues oneself the thing.
